UNTTED STATES PATENT @FETCH F. C. PAYNE,OF HEBRON, CONNECTICUT.

MEANS OF ADJUSTING- lVIOSQUITO-BARS.

Specicaton of Letters Patent No. 21,019, dated July 27, 1858-.

To all whom 2f may concern.'

Be it known that I, FREDERICK C. Parmi,

of Hebron, county of Tolland, and State of Connecticut, have invented certain new and useful Improvements in Devices for Adjusting Mosquito-Awnings, &c.; and I do hereby declare that the same is described and represented in the following specification and drawings, and to enable others skilled in the art to make and use the same I will proceed to describe the construction and operation, referring' to the drawings, in which the same letters .indicate like parts in each of the figures.

The nature of this improvement consists in attaching a slotted projection to the body of the sheave and securing therein a weighted arm, so that it will form what may be called a cramp holder to whatever passes between the lower end thereof up over the surface of the sheave.

In the accompanying drawings A, is the awning or netting.

B, represents the ceiling into which it is screwed at pleasure.

C, is a sheave arrangement (as ordinarily constructed for hanging lamps, ecc., with a balance weight on the opposite end of the chain or cord,) having a screw in the body thereof, for the purpose of securing it into the overhead ceiling.

D, is a slotted projection directly over the sheave E.

F, is a hanging weighted arm, secured in the slotted projection by a pin, a, the overbalancing weight of which causes the lower end CZ to rest against the sheave E.

Cr is a cord or band made fast to the ring or staple H, into the top of the awning or netting frame, thence up over the sheave, and down between it and the hanging arm, such a distance as shall make -it convenient for a person to take hold of and operate with the hand.

By pulling the end c, the awning is raised the desired height and held in that position by the arm F, and by pulling the end off to the right or left as shown at c it may be dropped and held, by bringing it back again over the sheave.

The advantage derived by this improvement, is the ready means afforded to travelers, of a simple, cheap and portable article, that may without trouble or inconvenience, be packed into a trunk ready for use in warm weather or when troubled with insects, and can be put up and taken down with but very little trouble.

I do not claim the sheave arrangement as used for hanging lamps &c., but

Vhat I do claim and desire to secure by Letters Patent is- The application of the slotted projection D, the hanging weighted arm F, in the manner and for the purpose substantially as herein set forth and described.
